San Francisco Bay Area-based ALO delivered two sets of their infectious brand of songs and jamming on August 6, but the news-headline of the day was the inaugural performance by Jay Lane & The Mayhem. Fresh off tour with Dead and Company, drummer Lane’s Mayhem trio presented a lively, improvisational, and supremely interesting hourlong 3 p.m. set that included material by Bob Dylan, Neil Young, John Lennon, Lane himself, and even composer John Williams.
